' JOHN HUDSON, OF NEWOASTLE-UPON-TYNE, ENGLAND. TRAM-CAR AND RAILWAY-CARRIAGE PLATFORM STEP-TREA'D.

Specification of Letters Patent.

Patented Nov. 21, 1905.

Application filed February 27, 1905. Serial No. 247,640.

T to whom it may concern:

Be it known that I, JOHN Henson, coachbuilder, a subject of the King of Great Britain, residing at Newcastleupon-Tyne, in the county of Northumberland, England, have invented certain new and useful Improvements in or Connected with Tram-Car and Railway- Carriage Platform Step-Treads,such being applicable to other purposes; and I do hereby declare the following to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in or connected with step-treads, and has particular reference to step-treads to be used in con nectionwith tram-cars and railway-carriage platforms. The step-treads may also be used inthe form of a mat or corridor-pavementor the like.

The object of the invention is to provide a simple and eflicient step-tread which shall be non-slipping, self-draining or cleansing. and of a durable nature, the wearing parts being interchangeable and reversible.

In order that my said invention may be more readily understood, I will now proceed to describe the same with reference to the accompanying drawings, in which Figure 1 is a sectional elevation, Fig. 2 a plan, and Fig. 3 a sectional end elevation, all of step-tread as applied. Fig. 4 is a sectional elevation, and Fig. 5 a plan, of modification of step-tread.

To the end in view I employ a series of rectangular or other suitably-shaped blocksA, preferably made of hard Wood and having beveled edges B all round. These blocks A are placed end-grain upward and are grooved, at the sides E to receive irons or stays F, by which they are held in position. These irons F are joined to end irons G, which are secured by bolts H and nuts J or other suitable device to the hangers or brackets K, by which the step-tread is fixed in position. The said blocks A are arranged in rows, and between the rows are open spaces L and purls or distance-pieces M, fixed in position by rods or bolts N. When the blocks A have become worn at the front edge, the blocks can be re versed or interchanged, as required. The said arrangement of blocks and connecting pieces can be used to produce a mat or tread for a shop floor or corridor or the like. The hangers in such cases are of course not required.

In the modification shown in Figs. 4 and 5 solid pieces of hard wood 0 are substituted for the end irons G, and the ends of the steptread are approximately rectangular instead of curved, as shown in Fig. 2. Also in the case of cars where a vertical rod is placed mid way on the platform step-tread a like solid piece of hard wood like those at the ends can be arranged at the center to form a base or support for such rod. Instead of the blocks A being grooved at the sides, as aforesaid, they may have holes at or about their centers, with rods passing through for securing them in position, as required.

What I claim as my invention, and desire to secure by Letters Patent, is

A step-tread composed of wooden blocks With beveled edges and arranged end-grain upward and provided with rectangular grooves in their sides, in combination with coacting rectangular bars adapted to fit in such grooves and to hold the blocks in position so that said blocks may be interchanged at will to compensate for wear, and purls or distancepieces between said bars whereby intervening open spaces are formed so that the tread is self-draining and cleansing, substantially as described.

In testimony whereofI afiix my signature in 5 presence of two witnesses.

JOHN HUDSON. Witnesses:

H. NIXON, THOMAS FENToN.
